Am I missing something with Xbox Live Messages?

I don't have Gold, as I refuse to pay to use Netflix and don't use my Xbox that much tbh. I recently figured "Hey, I'll message someone from my Lumia 920." The Xbox "app" said I needed to have Gold. I then tried from the Smart Glass app on my Android, and they got the message. Can anyone replicate this?

Am I wrong to think if anything it should be the opposite, as in a Lumia should be able to message with Silver, and an Android should only be able to with Gold?
